In many cases you want to recolor textures. All you have to do is to call the ColorPicker and apply a callback function that handles the colors returned by the ColorPicker. Normally you have a small frame with a texture and once you change the color in the ColorPicker the texture color updates via the callback function.FrameType: Frame (with an applied texture)

Sometimes it can be helpful to display data in a statusbar. They are similar to sliders, just without the option to edit. Like a progressbar or healthbar.FrameType: StatusBar
Template: ???
Widget: http://wowprogramming.com/docs/widgets/StatusBar

So working with tab buttons has to include this kind of onLoad script. Not sure why the script (on the template itself is the onload script) does not work properly since as you can see the tab button has a text applied. Currently not sure. Going to debug that.
